In this video, you'll learn how to download and run Windows Sysinternals Process Explorer to test all currently running executables on your Windows system against VirusTotal's 57 antivirus engines, which together offer the best accuracy you can ever get (with a small percentage of false positives that are pretty easy to spot).

Neither the Sysinternals Process Explorer software nor the VirusTotal service costs a cent. The whole setup process will take you about five minutes, and the scan, which you can execute any time you like, takes less than a minute.
